ADC1000 ISA-bus A/D Converter

The ADC1000 ISA-BUS A/D CONVERTER is a 12-bit, 8-channel, single-ended A/D card that connects our
spectrometers to desktop PCs. The PC2000 PC PLUG-IN SPECTROMETER has our 2048-element linear CCD-array
fiber optic spectrometer mounted onto an ADC1000. This sturdy combination fits easily into a slot in the PC. The
following are directions for installing your ADC1000 and PC2000. Because A/D converter installation goes hand­in-hand with software installation, you will find directions for installing OOIBase32 Spectrometer Operating
Software included in this section as well.

Each device in or connected to your computer is assigned specific settings; it’s similar to giving each device its
own name so that your computer will know what to call and how to recognize the device. In order for your
ADC1000 or PC2000 to work as a device in your computer, it has to be assigned a Base Address setting and an
IRQ setting. The default settings for each are:

Base Address (I/O Range): 768 decimal (300 hexadecimal)
IRQ (Interrupt Request): 07

These default values are set on the A/D converter. There are dip switches on the A/D board and their positions
determine the values. These default values are set in the operating software as well. Most of the time, these default
settings will work with your computer. However, if you have many devices installed in your computer, you may
have a conflict; other devices may be using these settings. If there is a conflict with another device in your
computer, you must change the positions of the switches on the A/D board and change the values in the software.

For the ADC1000 and PC2000, there is only one bank of switches on the A/D board: the Base Address may be
changed via the first 6 switches and the IRQ may be changed via the last 3 switches. To first check your computer
to see which settings are available, follow the instructions for your Windows operating system.

Find Available Base Address and IRQ Settings

1. Go to Start | Settings | Control Panel and double-click on the System icon.

2. Choose the Device Manager tab and double-click on “Computer” at the top of the list.

3. Under View Resources, find available settings -- numbers unassigned to hardware. Note these available

settings for both the Interrupt request (IRQ) and the Input/output (Base Address). When you first run
OOIBase32, you must enter these values in the “Configure Hardware” dialog box. (Remember that
Input/output settings are expressed in hexadecimal.)

!!

For most computers, the default settings work well. In the picture above left, it appears that the Printer occupies
IRQ 07, but for most computers, our A/D converters can share the 07 setting with a printer and conflicts will
not arise. All computers have multiple Base Address (Input/output) settings from which to choose.

Install the ADC1000 (or PC2000)

1. Turn off the computer and remove the computer cover.

2. Ground yourself to the computer chassis or power supply and remove the A/D card from its static-shielded bag.

3. If necessary, change the position of the switches on the A/D board. Position the switches to match the available
settings you found in the previous section -- numbers not being used by other hardware devices. See pages 5
and 6 for switch setting positions.

4. Find an open ISA-bus slot and remove the slot protector.

5. Insert the A/D card into an available expansion slot on the motherboard by gently rocking the card into the slot.
Make sure the card is fully seated in the motherboard before screwing the tab on the A/D card to the computer.
Do not bend the card or move it from side to side once it is seated in the slot.

6. For the ADC1000, attach the D37 end of the cable to the card and the D25 end to the spectrometer. For the
PC2000, attach the desired optical fiber to the SMA connector on the PC2000. Reinstall the cover.

Install OOIBase32

Before installing OOIBase32, make sure that no other applications are running.

1. Execute Setup.exe. At the “Welcome” dialog box, click Next>.

2. At the “Destination Location” dialog box, accept the default or choose Browse to pick a directory. Click Next>.

3. At the “Backup Replaced Files” dialog box, select either Yes or No. We recommend selecting Yes. If you select
Yes, accept the default or choose Browse to pick a destination directory. Click Next>.

4. Select a Program Manager Group. Click Next>. At the “Start Installation” dialog box, click Next>.

5. At the “Installation Complete” dialog box, choose Finish>.

6. When prompted to do so, restart your computer when the installation is complete.

Note:

In your spectrometer shipment box, you received a Wavelength Calibration Data Sheet wrapped around a
floppy diskette. The information on the diskette and the data sheet is the same and unique to your spectrometer.

Copy the calibration coefficients on the diskette to your hard drive or use the data sheet to enter this system-specific

data into OOIBase32. See the OOIbase32 documentation located at

www.oceanoptics.com\technical\opertinginstructions.asp for more information.

This appears to be the first time OOIBase32 has been executed. Please select a default spectrometer configuration

file from the following screen. This spectrometer configuration file will be used each time OOIBase32 is started.
